Double c core transformer (ED type)

ED core transformer is also called double C core transformer. From it's appearance, ED core transformer looks like two pieces of C core, and that is why we call it double C core transformer or dual C core transformer. ED core transformer has only one coil, and both primary windings and secondary windings are contained in this coil. The coil is surrounded by ED core. So, dual C core transformer is shell type transformer. Shell type transformer has firm structure.

Double C core output transformer

Double C core transformer is usually used for audio output transformer, and has excellent performance. Double C core transformer is called cut-core trasnformer by Japanese. It has larger flux saturation volume than traditional EI type transformer. Due to this, double C core transformer is not easy to get saturated, and has less overload distortion. Double C core transformer has strong and deep low frequency response. It is a good choice for audio output transformer.

ED core

0.23mm, 0.27mm, 0.30mm Hi-B oriented silicon steel strip will be adopted to make sure the best magnetic performance. It is made by a continuous silicon steel strip, no break point. The cut surface is smoothly processed, so there is less air gap and less flux leakage, which guaranteed the high magnetic performance.

Copper wire

OFC(Oxygen Free Copper) copper wire applied in our double C core transformers. OFC has no hydrogen embrittlement, and has a high conductivity. It is commonly used in audio equipment, vacuum electronic components, wire and so on.

Workmanship

From picking up a core, calculating an appropriate copper wire to delivery test, every single double C core transformer should undergo very strict processing flow. Only strict processing technics can guarantee a high quality double C core transformer. And only transformers from regular manufacturers can guarantee strict processing technics.
